説明:
(abstract)Electronic and crystal structures of YbCu, YbCu2, and YbCu6.5 were studied by high-resolution X-ray absorption spectroscopy and X-ray diffraction under pressure. YbCu exhibited a first-order transition with a sudden change in the Yb valence at 4 GPa without a structural transition. YbCu2 showed a gradual Yb valence change up to 11.8 GPa. Anomalous re-entrant valence transition to a lower valence state was found in YbCu6.5 at 3-4 GPa without a structural transition.
